Over time I have become increasingly irritated at the taking away of control over the various aspects of Cortana under Windows 10 Home, at least, while increasing control of almost everything else is offered.
On my machine in the early days I disabled the Personal Digital Assistant (PDA) feature of Cortana and then also switched off the "Search Online & include web results" toggle in "Cortana & search" settings which effectively turned what remained of Cortana into the old-style Windows Search.
In my work with blind and visually-impaired clients many of them want to do precisely that same thing, but with the advent of version 1703 the search online toggle is nowhere to be seen.
